Neuralgia is a painful disorder of the
nerves. Under the general heading of neuralgia are
trigeminal neuralgia (TN), atypical facial pain, and
postherpetic neuralgia (caused by
shingles or herpes). The affected nerves are responsible for sensing
touch,
temperature sensation and
pressure sensation in the
facial area from the
jaw to the
forehead. The disorder generally causes short episodes of excruciating
pain, usually for less than two minutes and on only one side of the face. The pain can be described in a variety of ways such as "stabbing," "sharp," "like lightning," "burning," and even "itchy". In the atypical form of TN, the pain can also present as severe or merely aching and last for extended periods. The pain associated with TN is recognized as one of the most excruciating pains that can be experienced.
